Gas recovery potential of sandstones from tight gas reservoirs

International Journal of Rock Mechanics and Mining Sciences, 2014
Abstract The aim of our experimental study is to characterize experimentally the petro-physical properties of a set of sandstones originating from different depths from a single tight gas field, in order to improve our knowledge on their gas recovery potential. The initial characterization of these sandstones is performed in the dry state, and in the

Acidizing flowback optimization for tight sandstone gas reservoirs

Journal of Natural Gas Science and Engineering, 2015
Abstract The physical properties of Sichuan tight sandstone formations include low porosity and low permeability. Fortunately, micro-fractures are well developed in this area, and the development of a reservoir is thus possible. Acidification can repair reservoir damage and improve single-well production; however, gas well production can change after

Well Spacing Optimization for Tight Sandstone Gas Reservoir

Proceedings of International Oil and Gas Conference and Exhibition in China, 2010
Abstract In the past five years, tight sandstone gas reserves amounted to almost 50% of the newly proved natural gas reserves of PetroChina Co., Ltd. and will be one of the main targets of natural gas production for a long term. Means to determine the reasonable well spacing are the key topics in the development of tight ...

Tight gas sandstone seismic monitoring, Rulison Field, Colorado

SEG Technical Program Expanded Abstracts 2008, 2008
Rulison Field is a basin-centered gas accumulation with a long production history dating back to the 1960s (Figure 1). Production is mainly from tight gas sandstones in the Williams Fork interval (Figure 2). Natural fractures significantly enhance the relative permeability to gas.

Microcrack Permeability in Tight Gas Sandstone

Society of Petroleum Engineers Journal, 1983
Abstract A model of stress-dependent permeability was developed on the basis of flow through cracks. The compliance of the cracks is controlled by elastic deformation of a Gaussian distribution of surface asperities, indented into the opposing crack face.

Tight Sandstone Reservoir Renaissance: Baimiao Gas Condensate Field

SPE Annual Caspian Technical Conference and Exhibition, 2014
Abstract Gas condensate has become very important because the liquid makes it a high-quality hydrocarbon fluid. Tight gas condensate reservoirs may contain large reserves, but can be extremely costly to develop. The Baimiao gas condensate reservoir is a deep, structurally complex, low- permeability play with a high condensate yield.

Pervasive Tight-gas Sandstone Reservoirs: An Overview

2008
The objectives of this chapter are threefold: (1) to provide a historical perspective on considerations of pervasive tight-gas accumulations, (2) to provide some observations on the present understanding of these accumulations, and (3) to anticipate where the industry is headed in the future.

Imaging tight gas sandstones in the East Texas Basin

First Break, 2008
Low porosity (tight) gas sands contain important commercial reserves but, unfortunately, are difficult to image seismically with the quality needed to drive an effective drilling programme. These reservoirs typically have a small contrast in acoustic impedance relative to the encasing shales which results in a subtle seismic signature.
